Increasing mobility and societal changes have made mobile, transportable and flexible architecture current again. Also, ecological awareness and technological development in all areas encourages to pursue new technical building applications. Prefabricated modular architecture has always been visionary as well as it always has been based on prefabrication in factories. This thesis examines prefabricated modules from the viewpoints of history, construction and architecture. Likewise, modular prefabricated architecture has been examined from the viewpoints of flexibility, ecological construction and transportability.

This thesis is based on a student competition held between autumn 2008 and early spring 2009. The intention of the competition was to examine prefabricated architecture and implementing it to mobile and flexible school construction. The objective of this thesis was to study the constraints and the possibilities of prefabricated modules and their implementation to school architecture. This thesis introduces the construction of the developed prefabricated module. Likewise, implementing prefabricated modules to extending existing school is showcased. The concepts of good learning environment have been taken into consideration in the design.
